If you've menstruated before then you can determine when you're about to get your period based on your average menstrual cycle length - this is normally around 28 days but everyone is slightly different.
Otherwise it's a little trickier to predict, everyone's bodies change leading up to menstruation - for example about two weeks prior to your period you will ovulate so your temperature will change and you will likely get fertile cervical mucus (an egg-white type discharge), after that you may notice your discharge thicken, changes to your mood, skin, breasts, etc. Many women don't learn to recognise these changes until they've menstruated for a while.
Uniformitarian geologists will use this method to determine which layer of rock formed at which time period of earth's history, and the order of the formation.
The easiest way to determine how much energy it takes to heat your house is to take a reading of your gas meter at 8:00 AM each day for two or three days during your coldest weather period and record the amount of gas used each 24 hours. Then knowing the volume of gas used each 24 hours, multiply the volume by the heating value to determine the energy used. Divide by 24 hours to get the average input per hour. Add 50% to that and you will have enough capacity for any winter day.You can also record the volume used during a short period of time that the heating device is on, 5 minutes is what I used, and determine what your current rate of energy input is. This can be done any time of year.

Yes you can get pregnant while on your period -
A wave length.
You can take a test the day after you miss a period
The length of the cord and gravity determine the period of a pendulum, which is the time it takes to complete one full swing. A longer cord will result in a longer period, while higher gravity will result in a shorter period.
One way to determine wave speed is by dividing the wavelength by the period of the wave. Another way is by multiplying the wavelength by the frequency of the wave.
the period is 2pi. period is 2pi/b and the formula is y=AsinBx.
Your body decides when you start your period nothing else. Hormones determine when this will happen.

No. Only hormones determine when you body has a period. What you drink or eat has nothing to do with it.
